Possibly the most distinctive dump valve around! The HKS Super Sequential Blow Off Valve (SSQV) is unique in both its sound and operation. Machined from billet Aluminium to the highest standards the SSQV can handle standard to very high boost pressures as a result of its unique 'pull type mechanism' whereby the boost actually helps hold the valve shut totally eliminating any boost leakage.
The SSQV produces a high pitched WRC style 'chirp' when releasing unwanted pressure helping the turbo continue to spin reducing any lag in between gear changes.
Model specific fitting kit included.
